QSL Card

A QSL card is a printed acknowledgment or confirmation exchanged between amateur radio operators after they make contact. Usually about the size of a postcard, it contains details such as the date, time, frequency, and call signs of both stations, along with location and signal strength information. These cards serve as a physical record of successful communication, often used for verification in radio awards or achievements. QSL cards foster international camaraderie and are collected by enthusiasts as keepsakes, celebrating their radio experiences across different regions and countries.
